Got a Trapeze Rigging Pull-up Bar from Craigslist OC and here's what I have to say:

It's awesome. I'm 165 and it holds me well for pull-ups, dips and body rows. In addition, I use a suspension trainer (formerly TRX but now another brand) and gymnastic rings. So long as I use these for purely vertical moves (ring dips, body rows, ring pushups), the trapeze rigging works quite well. It does make a little noise and sways ever-so-slightly but it's great.
